Sir Thedret had entered the fort a few weeks earlier also looking for the shield, but was caught by the mages inside who want the shield for their own use. They took his weapons and armor and locked him up, releasing him only to torture him in the hopes of getting information about the traps ahead. They where unable to get anything from him and were planning to kill him soon when the Hero showed up. If released from his cell he will share some knowledge about one of the puzzles and head out of the fort. He states that he is too weak to be of any help and will rejoin the Hero when he can.
